When I insert key. The unit turns on automatically with all the color and audio settings gone and the player keeps restarting every 10 to 20 seconds then i have to use a pin to do the hard reset.

What is the model? It probably has a thermal protection sensor that is not allowing it to start in order to protect itself. Did you specifically notify the manufacturer that you wanted it checked for a faulty thermal sensor causing a lower than normal thermal reset?
It may just be normal. Many phones, tablets, head units, home stereos, televisions and other modern electronics have these thermal protections that will not allow the device to be operated if they are above or even sometimes below, the specified thermal range determined by the manufacturer.
Perhaps you may want to consider window tinting to decrease the heat inside the vehicle or investing in a reflective shield that sits in the window in whichever direction the sun tends to be shining. I had similar problems with electronics left in my vehicle, even for an hour or so, until I did both of those things which decreased the internal temperatures by about 30°, dropping it from 125°F or more inside the car after sitting in direct sunlight to about 85-95°F.
